This configuration cannot be changed to Teensy 4.0 as this board does
not have Ethernet capability.

This configuration is similar to the nsh configuration with enabled
FlexPWM driver. Submodules 1 (pin 4) and 2 (pin 5) of FlexPWM2 are turn
on aswell as ultiple channel PWM output. Functionality can be tested

This configuration can be easily changed to work with Teensy 4.0 by
selecting ``CONFIG_TEENSY_40=y``.
